PORTABLE FAN AND OPERATING MACHINERY FOR SAME.

SPEC'EFICATIOE" forming part of Letters Patent No. 337,848, dated March 16, 1886.

Application filed July 17, 1885.

'To all whom it may concern.-

Be it known that we, ARTHUR \VrLLIAu MoCoiuAs and HENRY A. FrrzHUeH, citizens of the United States, residing at Austin, in the county of Travis and State of Texas, have invented certain new and useful Improvements in Portable Fans and Operating Machinery for same; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

Our present invention is an improvement in fans and mechanism for operating the same, to be used for general purposes.

Our fan is fluted or corrugated, (as seen in transverse section,) its lines of corrugation radiating from a common point. By this pecnliar formation we are enabled to concentrate the surrounding air during its movement, and direct and carry it in a body back and forth with better effect than may be done by a fan having aplane surface, which allows the air to escape laterally before it has had its full effect upon the objects which are intended to be reached. A heavy head or bar follows the zigzag or corrugated outline of the bottom of the fan, and serves as a weight to keep it tending downward toward a position of rest. The frame of the fan is made of metal covered with a durable fibrous or textile material.

The frame carrying our fan is supported upon standards provided with broad footings, which rest upon caster-wheels, by which the fan may be readily moved from place to place- The standards carry a train of gear-wheels which multiply power and connect with 1evers, arms, and so forth, which, in an indirect manner, give a reciprocating movement to the fan.

In the drawings, Figure 1 is a side elevation of our improved fan and driving mechanism, showing the several parts united and applied. Fig. 2 is a perspective view of our fan and the mechanism immediately connected with it. Fig. 3 is a diagram exhibiting the movement of the fan when operated upon by the movement of the levers which impart motion to it.

Similar reference-letters indicate like parts in all of the figures.

Referring to the drawings, A A represent Serial x0. 171,884. mi model.)

the uprights or standards of the frame, provided with broad footings to form a base.

These footings are provided with rollers or caster-wheels upon which the structure rests, and by which it may be rendered easily portable.

At a proper point upon one side of the uprights A is a bracket, L, near the outer end of which is pivoted a rocking lever, K. On one end of this rock -lever is an arm, N, which connects with the rod or pendulum F, which latter is pivoted upon a bar, B, at a point, Q, which bar is scoured in the uprights or standards A A.

The pendulum F, which is provided with a ball or weight, 0, is intended to regulate and equalize, in the usual manner, the movement of the operating mechanism for the fan.

serves as a pivot for the pendulum, is an arm, S, and to this arm is coupled a rod, U, which connects, in a manner hereinafter to be mentioned, with the fan.

A is a bent bar, which is hinged to the standards A A, and extends outward in the form of a U, to support the fan. This bent arm is held in position by rods P, hinged to the standards at R, and coupled to said arm A by hinge and sliding joint M.

\Vhen desirable, the arm A may be lowered or raised about its axis, and secured to position by clamping-screws in said joint M.

Sliding couplings X are provided upon the arm A and connected together by a bar, X, and upon this latter is hung by suspendingrods Y the fan Z, as shown.

A pitman, H, connects the rock-lever K and a crank, I, secured to a shaft journaled upon the standards A A. Upon this shaft, to which is attached the crank l, is fixed also gearwheel J, which connects with the main driving-shaft by wheel G, pinion 0, wheel E, pinion D, and driving-wheel D.

The fan Z is of a fixed, corrugated, or zig zag form, and is composed, as previously men tioned, of a metal frame covered with some suitable covering material.

E is the ribbing, which conforms to the sectional outline of the fan, and serves as a weight to steady the said fan in its movement and bring it to proper positions.

The operation of the fan may be described as follows: The driving-wheel, with its teeth meshing with pinion D, imparts motion to the pendulum and arm S through wheel E, pinion G, wheel G, pinion J, crank I, pitman H,

rock-lever K, and arm N. Rod U has slidejoints T and V to connect arm S with an arm, W, fixed. upon the bar X, and while the driving mechanism is in motion a rocking movement is imparted to said bar X and the susro pending-hooks Y. When the arm W is moved out, the suspending-rods move toward no (see diagram, Fig. 3) and carry the top of the fan with them, and the bottom, being weighted, follows to give the fan perpendicular position.

1 5 A reverse movement of arm W carries the top of the fan toward 2, and the lower portion, gravitating, gives the first serviceable sweep to the fan. This movement of the fan, which is indirect from the operating mechanism,

2o modifies to a considerable extent the wear and tear to the parts of the operating machinery.

The length of the are of movement to the fan may be regulated and changes made by means of sliding couplings T and V, when adjusted upon arms S and W, and clamped to position by clamping-screws.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is

0 1. In a fan to be operated by suitable driving mechanism, as set forth, the combination, with the straight and rigid upper bar and the zigzag or corrugated weighted lower bar, of suitable radial connecting-ribs and covering 3 5 materials, substantially as set forth.

2. The combination, with the U-shaped hinged arm A, supporting-bars P, by'which said arm may be held above or below a horiv zontal plane, the adjustable bar X, provided with sliding couplings X and suspending-rods 0 Y, of the bar B, uprights W and S, and rod U, by which said uprights W and S are adjustlably connected, as and for the purpose set fort v. v

3. The combination, with the upright stanehions B, fixed upon a suitable base, hinged arm A, hingedsupportiug-bars P, by which said arm may be held above or below a horizontal plane, the adjustable bar X, provided with sliding couplings X, suspending-rods Y, bar B, uprights W and S, and adjustably-connected rod U, of fan' Z, suspended upon said rods Y, all arranged asand for the purpose specified.

4. The combination, with the suspended fan, supporting-arm A, and connecting-rod U, substantially as set forth, of the driving'mechanism composed of rock-lever K, arm N, pendulum F O, pitman H, crank I, and the train of gear-wheels, all arranged substantially as'6'o and for the purpose set forth.

In testimony whereof we afiix our signatures in'presence of two witnesses.
